XTH30 affects etiolated hypocotyl growth in response to salt stress. (A) Seedlings germinated and grown for 2 d on 1/2 MS plates and transferred to 1/2 MS plates supplemented with or without 100 mM NaCl and grown for an additional 5 d in the dark. (B) Quantification of hypocotyl elongation of seedlings in (A). Error bars represent SD; n>15 seedlings per biological replicate. Similar results were observed in three independent experiments. The asterisk indicates a significant difference between xth30 mutants and wild type using unpaired Student’s t-test (**P<0.01). Scale bar indicates 3 mm.
